Abstract

A mineral insulated heating cable comprising two electrical conductors extending along the lengths of the cable and an array of heating elements distributed along the length of the cable and connected in parallel between the conductors. The heating cable is encased in a metal jacket which waterproofs the overall assembly, the jacket being electrically insulated from both the conductors and the heating elements by for example mica or glass fibre tape sheaths. The metal jacket is extruded directly onto the heating cable, or is extruded around and then drawn down onto the heating cable. Thus the structure can withstand high temperatures and yet is waterproof given the provision of the metal jacket.
